Description

Technical Field

[0001] The present invention relates to a biological sample processing system having a transport system configured to transport a container holder for supporting a container that houses a biological sample such as a liquid sample of a living body.

Background Art

[0002] In such a transport system, in a known manner, a plurality of container holders for supporting a container that houses a biological sample to be analyzed, a transport unit configured to transport the container holder, a holder guide element that defines a guide track, the holder guide element being configured to receive the container holder and guide the translational movement of the container holder along the guide track, a carriage guide element that defines a transport track extending along a support guide element, a self-propelled transport carriage movable along the transport track, the carriage guide element being configured to guide the self-propelled transport carriage during the movement of the self-propelled transport carriage along the transport track, and the self-propelled transport carriage being configured to translate the container holder along the guide track within the holder guide element when the self-propelled transport carriage moves along the transport track, a transport unit having, a plurality of receiving positions arranged along the guide track, each being configured to receive and at least temporarily store the container holder, and the self-propelled transport carriage being further configured to move the container holder laterally with respect to the guide track to move the container holder to or from one receiving position, having.

[0003] In such a transport system, the cumbersome operations of the operator are significantly restricted, and particularly when the container holder has to be transported between different analyzers and / or measuring devices, a high transport capacity and a high analysis speed are ensured.

[0004] Furthermore, if a self-propelled transport cart malfunctions, it can simply be replaced with another self-propelled transport cart, resulting in minimal downtime for the transport system and significantly limiting the time the bioanalysis system equipped with this transport system is unavailable in the analysis laboratory. It is also possible to equip the transport unit with two self-propelled transport carts, ensuring that one cart maintains consistent functionality (service) during reloading or maintenance of the other. Additionally, the presence of two self-propelled transport carts guarantees improved transport speed.

[0005] Furthermore, since the transport trolley is self-propelled, the transport track can be basically "passive," and is therefore determined by simple trolley guide elements such as guide rails. This greatly simplifies the transport system, reduces costs, improves the reliability of the system, and makes it easier to configure and install quickly and easily. [Overview of the project] [Problems that the invention aims to solve]

[0006] However, when the container holder is driven in translation by the self-propelled transport cart, friction between the container holder and the holder guide element generates noise, which can be unpleasant for the operator. Furthermore, this friction increases the power consumption of the self-propelled transport cart, which in turn affects the autonomy of the cart's battery.

[0007] Furthermore, when the container holder moves from the guide track to the receiving position by the self-propelled transport trolley (and therefore moves perpendicular to the transport direction of the self-propelled transport trolley), the container holder may tilt vertically due to friction on the underside of the container holder at the holder guide element. This may result in the container holder not being positioned optimally at the receiving position, which in turn may affect the gripping of the container holder by the loading mechanism used at the receiving position.

[0008] The present invention aims to resolve these problems.

[0009] Therefore, the technical problem underlying the present invention is to provide a biological sample processing system equipped with a transport system that has a simple, economical, and reliable structure, while ensuring high transport capacity, optimized analysis speed, and easy and rapid maintainability. [Means for solving the problem]

[0010] For this purpose, the present invention relates to a biological sample processing system such as a biological analysis system, and this system is Multiple container holders for holding containers containing biological samples such as liquid samples of living organisms, A transport unit configured to transport a container holder, the transport unit comprising a trolley guide element that forms a transport track and a self-propelled transport trolley that can move along the transport track, wherein the trolley guide element is configured to guide the self-propelled transport trolley during its displacement along the transport track, the transport unit comprising a trolley body and configured to move the container holder along a movement path when the self-propelled transport trolley moves along the transport track, A plurality of receiving positions arranged along a movement path and offset laterally with respect to the movement path, each of which is configured to receive and at least temporarily store a container holder, and further configured to move the container holder laterally with respect to the movement path so that the self-propelled transport trolley moves the container holder to or from the receiving position, A transport system having, The transport unit comprises at least one analyzer and / or measuring device arranged along the transport unit and configured to perform blood tests, The self-propelled transport trolley has two gripping arms spaced apart from each other, and the two gripping arms are mounted to be movable between a gripping position configured to be close to each other and to grip and lift a container holder placed in one of the receiving positions, and a release position configured to be spaced apart from each other and to release the container holder and place the container holder in one of the receiving positions, and the self-propelled transport trolley is configured to move the container holder gripped and lifted by the gripping arms along the movement path as the self-propelled transport trolley moves along the transport track, and each gripping arm includes a lifting member, the lifting member being received into two receiving recesses provided on two lateral surfaces of a container holder facing each other when the gripping arm moves to the gripping position, and lifting the container holder.

[0011] Such a configuration of a transport system, particularly a self-propelled transport trolley, allows the container holder to be moved at a distance from the trolley guide element, thereby avoiding friction between the container holder and the trolley guide element during displacement of the container holder along the movement path and during displacement of the container holder laterally relative to the movement path (for example, when loading the container holder into the receiving position).

[0012] As a result, the battery life of the self-propelled transport vehicle is improved, and the battery charging cycle can be spaced further apart. Therefore, the downtime of the self-propelled transport vehicle is significantly reduced.

[0013] Furthermore, the absence of friction between the container holder and the trolley guide element during the displacement of the container holder along the movement path significantly reduces noise generated by the transport system, greatly improving operator comfort.

[0014] Moreover, while the container holder is displaced laterally with respect to the movement path (particularly when loading the container holder into the receiving position), the absence of friction between the container holder and the carriage guide elements ensures optimal positioning of the container holder at the receiving position, thus ensuring optimal gripping of the container holder by the loading mechanism used at the receiving position.

[Figure 18] Figure 18 is a side view of the self-propelled transport cart from Figure 2 in the state where the container holder is gripped and raised. [Modes for carrying out the invention]

[0062] In this specification, the terms “horizontal” and “vertical” are used to describe a self-propelled transport cart in a usage scenario in which the self-propelled transport cart is placed on a flat, horizontal surface with its drive wheels.

[0063] Figure 1 shows a bioanalysis system 1 for in vitro analysis, more specifically an automated bioanalysis system, having a transport system 2 including a plurality of container holders 3 and a transport unit 4 configured to transport the container holders 3. The bioanalysis system 1 further includes a plurality of analyzers and / or measuring devices 5 arranged along the transport unit 4 and configured to perform blood tests.

[0064] For example, each analyzer and / or measuring device 5 may have one or more modules selected from, in particular, a spectrophotometric reading module, a fluorescence reading module, a luminescence reading module, a cytometry module, and a coagulation measurement module.

[0065] Furthermore, the transport system 2 includes a storage device 6, also called a loading device, which is arranged along the transport unit 4 and configured to store the container holder 3.

[0066] The transport system 2 further comprises a plurality of receiving areas 7 arranged along the transport unit 4, each including at least one receiving position 8 configured to at least temporarily receive and store container holders 3.

[0067] Advantageously, one receiving area 7 is positioned close to the storage device 6, and another receiving area 7 is positioned close to the analyzer and / or measuring device 5, respectively.

[0068] According to the embodiment shown in the figures, each receiving area 7 (see Figures 1 and 11-16) includes two receiving positions 8, namely a first receiving position 8.1 and a second receiving position 8.2, which are offset from each other along the transport unit 4. Advantageously, each analytical and / or measuring device 5 has a loading module (not shown) configured to load a container holder 3 positioned at the first receiving position 8.1 of its respective receiving area 7 into its analytical and / or measuring device 5, and an unloading module (not shown) configured to move a container holder 3 pre-loaded into its analytical and / or measuring device 5 at the second receiving position 8.2 of its respective receiving area 7. Similarly, the storage device 6 has a drive mechanism (not shown) configured to move a container holder 3 stored in the storage device 6 at the second receiving position 8.2 of its respective receiving area 7.

[0069] According to the illustrated embodiment, each receiving area 7 has a first guide wall 13 and a second guide wall 14 that are offset from each other and extend substantially perpendicularly. The first and second guide walls 13 and 14 form a guide track that extends along the transport unit 4 and are configured to guide the container holder 3 as it translates along the guide track. Advantageously, the first and second receiving positions 8.1 and 8.2 of the receiving area 7 are located at opposite ends of each guide track, respectively, with the first guide wall 13 located opposite each of the second guide walls 14 and having a passage opening 15 for the passage of the container holder 3.

[0070] As shown in detail in Figures 10 and 11, each container holder 3, also called a rack, cassette, or carrier, is intended to hold multiple containers 16 containing biological liquid samples to be analyzed, such as blood, plasma, or blood serum samples. Advantageously, the containers 16 are sample tubes.

[0071] Each container holder 3 is generally parallelepiped in shape and extends in a direction consistent with the extension direction. More specifically, each container holder 3 has two opposing longitudinal surfaces 17 and two opposing transverse surfaces 18.

[0072] Each container holder 3 has a base 3.1 and a container receiving portion 3.2. Advantageously, the container receiving portion 3.2 of each container holder 3 has a symmetrical plane extending laterally with respect to the direction in which the container holder 3 extends. Therefore, the container holders 3 can be loaded into the storage device 6 indiscriminately.

[0073] Each container holder 3 includes a plurality of preferably cylindrical receiving compartments 19 aligned in the direction of extension of the container holder 3. Advantageously, the receiving compartments 19 are open upward to facilitate the insertion and removal of containers 16 into and out of the receiving compartments 19. Advantageously, the lower part of each receiving compartment 19 is provided with, for example, an elastically deformable retaining member 20, configured to hold the container 16 within the receiving compartment 19. Such a configuration of the retaining member 20 prevents damage to identification codes, such as those provided on identification tags, carried by the container 16.

[0074] Each container holder 3 has a plurality of reading windows 21 that allow for the optical reading of identification codes carried by containers 16 received by the container holder 3. Advantageously, two reading windows 21 are added to each receiving compartment 19 to allow optical reading from each side of the container holder 3.

[0075] Furthermore, each container holder 3 has two receiving recesses 22 provided on each of its two lateral surfaces 18, the function of which will be explained below. Advantageously, each receiving recess 22 is provided on the upper part of each lateral surface 18.

[0076] As shown in Figures 11 to 16, the transport unit 4 has a trolley guide element 23 that forms a straight transport track. For example, the trolley guide element 23 may have a horizontal and planar support surface 23a and two guide rails 23b fixed to the support surface 23a. Advantageously, the transport track is parallel to the first and second guide walls 13 and 14 belonging to each receiving area 7. However, according to a modified version of the present invention, the transport track may have a curved portion.

[0077] Furthermore, the transport unit 4 has a self-propelled transport trolley 24 that can move along the transport track. The self-propelled transport trolley 24 is configured to move the container holder 3 along a travel path parallel to the transport track as the self-propelled transport trolley 24 moves along the transport track, and to move the container holder 3 to or from a receiving position 8 that is shifted laterally with respect to the travel path, thereby moving the container holder 3 laterally with respect to the travel path. Advantageously, the self-propelled transport trolley 24 is configured to hold the container holder 3 substantially vertically while moving along the travel path.

[0078] More specifically, the trolley guide element 23 is configured to guide the self-propelled transport trolley 24 as it displaces along the transport track. Advantageously, the two guide rails 23b are configured to cooperate with two guide grooves 25 (see Figure 3) provided on the underside of the self-propelled transport trolley 24.

[0079] As shown in detail in Figures 2 and 3, the self-propelled transport trolley 24 comprises a trolley body 26 and drive wheels 27 rotatably mounted on the trolley body 26 and configured to roll on the support surface 23a of the trolley guide element 23. Each drive wheel 27 has a rotation axis that extends substantially horizontally. Advantageously, the self-propelled transport trolley 24 has a pair of drive wheels positioned close to the first longitudinal end of the trolley body 26 and a pair of drive wheels positioned close to the second longitudinal end of the trolley body 26.

[0080] The self-propelled transport trolley 24 has a rotary drive mechanism 28 configured to rotate the drive wheels 27. For example, the rotary drive mechanism 28 has a drive motor rotatably connected to the drive wheels 27.

[0081] Each drive wheel 27 can be driven to rotate in a first rotational direction and in a second rotational direction opposite to the first rotational direction. Therefore, the self-propelled transport trolley 24 can move along the transport track in a first travel direction and in a second travel direction opposite to the first travel direction.

[0082] The self-propelled transport trolley 24 further includes support elements 29, for example in the form of support frames, which are translationally movable relative to the trolley body 26 in the direction of horizontal movement and mounted perpendicular to the transport track. Advantageously, the support elements 29 are translationally guided by a pair of guide rods 30.

[0083] Furthermore, the self-propelled transport trolley 24 has two gripping arms 31 that are spaced apart from each other along the longitudinal direction of the self-propelled transport trolley 24. The two gripping arms 31 are pivotably mounted on the support element 29 about two vertical pivots, each around which they are located. Advantageously, the two gripping arms 31 are movable within a substantially horizontal plane of movement.

[0084] The two gripping arms 31 are rotatably mounted so as to move between a gripping position, where the gripping arms 31 are positioned close to each other (see Figures 11-16 and 18) and are configured to grip and lift a container holder 3 located in one of the receiving positions 8, and a release position, where the gripping arms 31 are positioned far apart from each other and release the container holder 3, placing it in one of the receiving positions 8 (see Figures 3-5 and 17). Thus, the self-propelled transport trolley 24 is configured, more specifically, to move the container holder 3, gripped and lifted by the gripping arms 31, along the transport path as the self-propelled transport trolley 24 moves along the transport track.

[0085] Each gripping arm 31 has a gripping portion 32 with a support surface 33 configured to exert a supporting force on each lateral surface 18 of the container holder 3 when the gripping arm 31 is in the gripping position. Advantageously, each gripping portion 32 is located at the free end of each gripping arm 31. As shown in detail in Figure 3, the gripping portions 32 of the two gripping arms 31 protrude from the side surface 26.1 of the trolley body 26 when the two gripping arms 31 are in the gripping position.

[0086] Furthermore, each gripping arm 31 has a lifting member 34, such as a lifting projection, extending from the support surface 33 of its respective gripping portion 32. Advantageously, each lifting member 34 has a lifting inclined surface 35 that is inclined with respect to the vertical.

[0087] The lifting members 34 are configured to be received by the receiving recesses 22 provided in the container holder 3 when the gripping arm 31 is in the gripping position, and when the gripping arm 31 moves to the gripping position, the lifting inclined surface 35 cooperates with the complementary surface formed by the receiving recesses 22, thereby lifting the container holder 3.

The battery 38 is also configured to supply power to an electronic control unit 40 provided on the self-propelled transport trolley 24 and configured to control the operation of the self-propelled transport trolley 24. More specifically, such an electronic control unit 40 has an electronic circuit board equipped with a microprocessor.

[0095] According to the illustrated embodiment, the battery 38 is rechargeable and can be charged, for example, by contact or induction. For this purpose, the transport system 2 includes at least one charging area 39, which is configured to electrically charge the battery 38 when the self-propelled transport trolley 24 is positioned within its charging area. Advantageously, the transport system 2 includes two charging areas 39, each located at the ends of a transport track, and charging coils are provided close to each of the longitudinal ends of the self-propelled transport trolley 24.

[0096] According to one embodiment of the present invention, the transport system 2 has a plurality of positioning markings (not shown) arranged on the transport track. For example, the transport system 2 has positioning markings facing each receiving position 8 and each passage opening 15.

For example, each positioning marking can be formed by an optical barrier, a barcode, a QR code (registered trademark), an RFID tag, or a notch in a guide rail 23b.

[0098] According to one embodiment of the present invention, the self-propelled transport cart 24 further has a determination means configured to determine the position of the self-propelled transport cart 24 along a transport track in accordance with the distance the self-propelled transport cart 24 has traveled. For this purpose, the drive wheels 27 can be configured to drive encoders that enable the measurement of the distance traveled by the self-propelled transport cart 24, and the control of the movement of the self-propelled transport cart 24 can be configured to be servo-controlled by an electronic control unit 40 in particular in accordance with this distance traveled.
